Typical applications include industrial sensor interfaces, battery-monitoring systems, portable instrumentation, and data-acquisition front-ends where a moderate sample rate and 10-bit resolution are sufficient.
The input multiplexer provides two differential or four single-ended channels. The MUX-S/H-ADC configuration samples one channel per conversion.
Yes. The analog and digital supply range is 2.7V to 5.25V, so a 5V rail is within spec. The external reference sets the full-scale input range independently.
Both. The internal MUX can be configured for two differential inputs or four single-ended inputs, selected by the control word sent over SPI.
